NASA audio reveals what space really sounds like

Ridley Scott's Alien may have had you believe that in space, no one can hear you scream. But it turns out that actually, there are some kinds of sounds flying around out there. We're told that space is a vacuum and there's no medium for sound to travel through, and while that's mostly true, there are a few particles and sound waves bobbing around.

And you know what else? They're terrifying AF.

Just in time to scare us for Halloween, NASA has released a playlist on Soundcloud titled Spooky Sounds from Across the Solar System. It features 22 "space sound" tracks, giving us a whole new insight into what goes on in our solar system.

"Soaring to the depths of our universe, gallant spacecraft roam the cosmos, snapping images of celestial wonders," the space agency said, in an introduction of how they captured the sound.

"Some spacecraft have instruments capable of capturing radio emissions. When scientists convert these to sound waves, the results are eerie to hear."

So they're not sounds in the traditional sense, but more like audio "interpretations" of radio waves that are emitted from planets and the other mysterious things in space. What we're hearing are sounds of planets that seem to howl, liquid helium that sounds like it's whistling, and the low, ominous sounds of light curve waves that's enough to make your skin crawl.

The track Plasmaspheric Hiss sounds like some horrendous space monster breathing heavily before it's about to devour you, while Cassini: Saturn Radio Emissions #2 is what you'd imagine alien communication to sound like. But, turns out they're not aliens, but rather audio of radio waves that are emitted from the ringed planet.

"Saturn is a source of intense radio emissions, which were monitored by our Cassini spacecraft," NASA wrote to describe the track. "The radio waves are closely related to the auroras near the poles of the planet. These auroras are similar to Earth's northern and southern lights. This is an audio file of radio emissions from Saturn."

Gassy giant Jupiter sets off some freakish high-pitched glitch sounds in Jupiter Sounds 2001, while Kepler: Star KIC7671081B could be mistaken for something from a horror movie soundtrack.

Other than the Spooky Sounds playlist, NASA's Soundcloud is filled with audio treasures. It features a bunch of different sounds from current missions as well as well-known flights in history. Neil Armstrong's "One small step for (a) man, one giant leap for mankind" is there, as well as the now-catchphrase "Houston, we've had a problem", which NASA adorably suggests you download to play "every time you make an error on your computer".

Well, thanks for dropping your new tracks guys, it's just in time for Halloween tomorrow. I know a bunch of us will be turning to the playlist to play for Trick or Treaters or simply to blast in the background of our parties. Cheers!
